Abstract

An absolute standardisation of 89Zr was performed alongside determination of gamma emission intensities and half-life. The collected data were evaluated alongside complementary works from previous publications and new recommended nuclear data values are presented including a new evaluated T1/2 = 78.361(25) h and new absolute intensities for gamma transitions resulting from its decay to 89Y. Dial settings for commercially available radionuclide calibrators are also presented and show a relative difference of approximately 3% compared to previously published values.
